【方案一】bat + reg + vbs

代码如下:

@echo off

::演示：删除指定路径下指定天数之前（以文件夹的最后修改日期为准）的文件夹。

::如果演示结果无误，把rd前面的echo去掉，即可实现真正删除。

::本例调用了临时vbs代码进行日期计算

::本例为兼容不同的日期格式，调用reg命令（xp系统自带）统一设置日期格式，

::处理完毕之后再把日期格式恢复成原来的状态。

rem 指定待删除文件夹的存放路径

set srcdir=c:/test

rem 指定天数

set daysago=1

for /f skip=2 delims= %%a in ('reg query hkey_current_user/control panel/international /v sshortdate') do (

set regdateold=%%a

)

set regdateold=%regdateold:~-8%

reg add hkey_current_user/control panel/international /v sshortdate /t reg_sz /d yyyy-m-d /f>nul

>%temp%/dstdate.vbs echo lastdate=date()-%daysago%

>>%temp%/dstdate.vbs echo fmtdate=right(year(lastdate),4) ^& right(0 ^& month(lastdate),2) ^& right(0 ^& day(lastdate),2)

>>%temp%/dstdate.vbs echo wscript.echo fmtdate

for /f %%a in ('cscript /nologo %temp%/dstdate.vbs') do (

set dstdate=%%a

)

set dstdate=%dstdate:~0,4%-%dstdate:~4,2%-%dstdate:~6,2%

for /d %%a in (%srcdir%/*.*) do (

if %%~ta leq %dstdate% (

if exist %%a/

echo rd /s /q %%a

)

)

)

reg add hkey_current_user/control panel/international /v sshortdate /t reg_sz /d %regdateold% /f>nul

pause

【方案二】bat + reg + ritchie lawrence 日期函数

代码如下:

@echo off

::演示：删除指定路径下指定天数之前（以文件夹的最后修改日期为准）的文件夹。

::如果演示结果无误，把rd前面的echo去掉，即可实现真正删除。

::本例调用了 ritchie lawrence 的日期函数进行日期计算

::日期转换的核心算法请参考http://bbs.bathome.cn/thread-3056-1-1.html

::本例为兼容不同的日期格式，调用reg命令（xp系统自带）统一设置日期格式，

::处理完毕之后再把日期格式恢复成原来的状态。

rem 指定待删除文件夹的存放路径

set srcdir=c:/test

rem 指定天数

set daysago=1

for /f skip=2 delims= %%a in ('reg query hkey_current_user/control panel/international /v sshortdate') do (

set regdateold=%%a

)

set regdateold=%regdateold:~-8%

reg add hkey_current_user/control panel/international /v sshortdate /t reg_sz /d yyyy-m-d /f>nul

call :datetodays %date:~0,4% %date:~5,2% %date:~8,2% passdays

reg add hkey_current_user/control panel/international /v sshortdate /t reg_sz /d %regdateold% /f>nul

set /a passdays-=%daysago%

call :daystodate %passdays% dstyear dstmonth dstday

set dstdate=%dstyear%%dstmonth%%dstday%

set dstdate=%dstdate:~0,4%-%dstdate:~4,2%-%dstdate:~6,2%

for /d %%a in (%srcdir%/*.*) do (

if %%~ta leq %dstdate% (

if exist %%a/

echo rd /s /q %%a

)

)

)

reg add hkey_current_user/control panel/international /v sshortdate /t reg_sz /d %regdateold% /f>nul

pause

【方案三】bat + vbs

代码如下:

@echo off

::演示：删除指定路径下指定天数之前（以文件夹的最后修改日期为准）的文件夹。

::如果演示结果无误，把rd前面的echo去掉，即可实现真正删除。

::本例调用了临时vbs代码进行日期计算，并统一设置系统日期格式，处理完毕

::之后再把日期格式恢复成原来的状态。摆脱了对reg命令（xp系统自带）的依赖。

rem 指定待删除文件夹的存放路径

set srcdir=c:/test

rem 指定天数

set daysago=1

>%temp%/backupdate.vbs echo set wshshell = wscript.createobject(wscript.shell)

>>%temp%/backupdate.vbs echo wscript.echo wshshell.regread (hkey_current_user/control panel/international/sshortdate)

for /f %%a in ('cscript /nologo %temp%/backupdate.vbs') do (

set regdateold=%%a

)

>%temp%/unifydate.vbs echo set wshshell = wscript.createobject(wscript.shell)

>>%temp%/unifydate.vbs echo wshshell.regwrite hkey_current_user/control panel/international/sshortdate, yyyy-m-d, reg_sz

cscript /nologo %temp%/unifydate.vbs

>%temp%/dstdate.vbs echo lastdate=date()-%daysago%

>>%temp%/dstdate.vbs echo fmtdate=right(year(lastdate),4) ^& right(0 ^& month(lastdate),2) ^& right(0 ^& day(lastdate),2)

>>%temp%/dstdate.vbs echo wscript.echo fmtdate

for /f %%a in ('cscript /nologo %temp%/dstdate.vbs') do (

set dstdate=%%a

)

set dstdate=%dstdate:~0,4%-%dstdate:~4,2%-%dstdate:~6,2%

for /d %%a in (%srcdir%/*.*) do (

if %%~ta leq %dstdate% (

if exist %%a/

echo rd /s /q %%a

)

)

)

>%temp%/recoverdate.vbs echo set wshshell = wscript.createobject(wscript.shell)

>>%temp%/recoverdate.vbs echo wshshell.regwrite hkey_current_user/control panel/international/sshortdate, %regdateold%, reg_sz

cscript /nologo %temp%/recoverdate.vbs

pause

【方案四】字符串截取

代码如下:

@echo off

::演示：删除指定路径下指定天数之前（以文件夹名中包含的日期字符串为准）的文件夹。

::如果演示结果无误，把rd前面的echo去掉，即可实现真正删除。

::本例假设文件夹名中包含的日期字符串（比如：archive-2009-12-25）

rem 指定待删除文件夹的存放路径

set srcdir=c:/test

rem 指定天数

set daysago=1

>%temp%/dstdate.vbs echo lastdate=date()-%daysago%

>>%temp%/dstdate.vbs echo fmtdate=right(year(lastdate),4) ^& right(0 ^& month(lastdate),2) ^& right(0 ^& day(lastdate),2)

>>%temp%/dstdate.vbs echo wscript.echo fmtdate

for /f %%a in ('cscript /nologo %temp%/dstdate.vbs') do (

set dstdate=%%a

)

set dstdate=%dstdate:~0,4%-%dstdate:~4,2%-%dstdate:~6,2%

setlocal enabledelayedexpansion

for /d %%a in (%srcdir%/*.*) do (

if %%~ta leq %dstdate% (

set folderdate=%%~na

set folderdate=!folderdate:~8,10!

if !folderdate! leq %dstdate% (

if exist %%a/ (

echo rd /s /q %%a

)

)

)

)

endlocal
